How to do a lumber takeoff, then price it in 30 seconds

By Simon Lafortune, Co-founder, Buildsavr · July 3, 2026

A lumber takeoff is where a build becomes a number. You go through the plan, count every piece, and end up with a list you can actually buy from. Framers, GCs, and serious DIYers all do some version of it, because the alternative is guessing, and guessing means either too many trips or a pile of leftover lumber.

But the takeoff is only step one. Once you have the list, you still have to price it, and that is where the real money hides. This is how to do a clean takeoff, and how to turn it into a priced, store-by-store buying plan in about 30 seconds instead of an afternoon.

What is a lumber takeoff?

A lumber takeoff is the count of every piece of lumber and framing material a project needs, pulled off the plans or measured on site. It is the lumber half of a full material takeoff. The output is a list, each line specific enough to order and priced by the piece: species, grade, treatment, dimension, and quantity.

The word "takeoff" just means you are taking the quantities off the drawings. On a framing job that means studs, plates, headers, joists, rafters or trusses, sheathing, and the fasteners and connectors that hold it together. Done right, the takeoff is what you hand to a supplier, or paste into a tool, to get a real price.

  • Framing lumber: studs, top and bottom plates, headers, blocking
  • Structure: joists, rafters or trusses, beams, posts
  • Sheathing: wall and roof OSB or plywood, subfloor
  • Connectors and fasteners: joist hangers, structural screws, nails, hurricane ties
  • A waste factor: usually 5 to 10 percent on cut framing lumber

How to do a lumber takeoff, step by step

The method is the same whether you are framing a shed or a two-storey. Work the plan in the order you build it, be specific, and count twice.

  • Walls first. Count studs at your spacing (usually 16 inches on center), add plates (one bottom, two top), then headers for every opening.
  • Then the horizontal structure. Joists and rafters at spacing, plus rim joists, beams, and posts.
  • Sheathing by area. Take the wall and roof square footage, divide by 32 (a 4x8 sheet), round up.
  • Connectors and fasteners. One hanger per joist end, structural screws by the box, nails by the bag. These get forgotten and they add up.
  • Add waste. Tack on 5 to 10 percent to cut lumber for offcuts and mistakes.
  • Write it so it can be priced. "2x6x8 SPF #2 kiln-dried, qty 42" is orderable. "some 2x6s" is not.

The step everyone skips: pricing the takeoff

Here is the part that quietly costs the most. You finish a clean takeoff, then you send the whole thing to one supplier, or buy it all at one big-box, and call it done. Convenient, but no single yard is cheapest on everything.

One store has the best number on framing lumber this week and marks up the connectors. Another is cheap on sheathing and pricey on pressure-treated. Prices move week to week and vary by region. So the cheapest way to buy a takeoff is never one store, it is a different store per line, and pricing that by hand across every retailer is a job nobody actually does for a full list.

Feed your takeoff to the AI plan reader

This is exactly what Buildsavr is built to do. You give it your takeoff however you already have it, typed out, a photo of a handwritten list, an Excel sheet, a PDF, or just by chatting, and the AI plan reader reads it, matches every line to the right product, and prices it across every major retailer near you at once.

What comes back is a buying plan: line by line, which store is cheapest, your total, and how much you save versus buying everything in one place. In Quebec today it prices your list across Home Depot, Rona, Canac, BMR, Patrick Morin, Home Hardware, and more, all at the same time. The whole thing takes about 30 seconds.

You stay in control. If one line is a few dollars cheaper across town and not worth the drive, keep it with the rest of your order. The plan gives you the numbers so it is your call, not a guess.

Why this matters more on a takeoff than a shopping run

A grocery-sized list, a few dollars saved is nice. A framing takeoff worth thousands, a few percent is real margin, and it repeats on every job. That is the whole reason to stop pricing takeoffs by hand: the bigger the list, the more one-store buying costs you, and the less realistic it is to check every retailer yourself.

For a contractor, pricing the package before ordering protects the bid. For a DIYer framing a garage or a deck, it is the difference between paying list price and paying what the job should actually cost.

Frequently asked questions

What is a lumber takeoff?
A lumber takeoff is a count of every piece of lumber and framing material a project needs, taken off the plans or measured on site. Each line is specific enough to order (species, grade, treatment, dimension) with a quantity and a small waste factor. It is the list you hand to a supplier or paste into a pricing tool to get a real cost.
How do I do a lumber takeoff?
Work the plan in build order. Count wall studs at your spacing plus plates and headers, then joists, rafters and beams, then sheathing by area (square footage divided by 32 for 4x8 sheets), then connectors and fasteners. Add 5 to 10 percent waste on cut lumber, and write each line specifically enough to price, like "2x6x8 SPF #2, qty 42."
How do I price a lumber takeoff across stores?
Instead of pricing each item at each retailer by hand, give your takeoff to Buildsavr (typed, photo, Excel, PDF or chat). Its AI plan reader matches every line and prices it across every major retailer near you at once, then returns a store-by-store buying plan with the cheapest place for each item and your total. It is live in Quebec and expanding across Canada and the US.
Does the AI read a photo of a handwritten takeoff?
Yes. You can snap a photo of a handwritten or printed list, or drop an Excel or PDF, and the AI reader parses it into line items, matches each to the right product, and prices it. You can also just chat your list and an AI agent helps fill in anything you forgot before it prices everything.
How long does it take?
About 30 seconds from handing over your takeoff to getting a priced, store-by-store buying plan. The slow part, pricing every line across every retailer, is the part the tool automates.
